The problem with the Summoner is their DPS is poorly optimized for fights longer then 2 min. Summoner's DPS slowly ramps up reaches it's maximum after 12.5s then steadily drops to its minimum and never recovers even with Fester and good mp management. SE should reduce the cool down on Enkindke to 30s because right now it does the same damage as Fester but on an ungodly long cool down.
